Hi there people.
I have noticed a number of small to large black spots lumps on the shaft of my penis and bag. They are grouped togeter and in various places. The number of spot has incresed from 3-4 to over 18!! Is this a sign of an STD?? They do not hurt or cause uncomfort, if it is a STD like herps or genatal warts is there any ways to get rid of them totally!!
